HAIRPIN.

Specification of Letters Patent.

Patented Oct. 4, 1921.

Application filed March 20, 1920. Serial No. 367,318.

To all whom it may concern:

Be it known that I, FRED WALKER, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented new and useful Improvements in Hairpins, ofwhich the following is a specification.

My invention relates to a new and useful improvement in ahair pin, andhas for its object to. provide an exceedingly simple and effectivedevice of this character which is so constructed that when placed in thehair the strands of hair will be caught between the corrugationsregardless of the direction in which such strands of hair are run.

Another object of the invention is to provide a hair pin having fourtangs all of which are corrugated the corrugations on two of the tangsrunning in one direction while the corrugations on the other two tangsrun in the opposite direction or at right anthe first named tangs.

A further object of the invention is to provide a hair pin having twocentral tangs provided with corrugations lying in one direction and twoouter tangs having corrugations lying at right angles to thecorrugations of the central tangs.

With these ends in view, this invention consists in the details ofconstruction and combination of elements hereinafter set forth and thenspecifically designated by the claim.

In order that those skilled in the art to which this inventionappertains may understand how to make and use the same, I will describeits construction in detail, referring by numerals to the accompanyingdrawing forming a part of this application, in which Figure 1, is afront elevation of a hair pin embodying my invention.

Fig. 2, is an edge view thereof.

In carrying out my invention as here embodied, 2 represents a hair pinformed of suitable material such as wire bent upon itself to form twoparallel central tangs 3 the ends being then bent outward upon saidcentral tangs to form two outer tangs 4 the latter being preferablyslightly longer than the centraltangs as shown in Fig. 1;

The central tangs 3 are eachv corrugated in the same directionthroughout any desirable portion of the length as indicated by 5, Whilethe outer tangs 4 are also corrugated throughout any desirable portionof their length as indicated by 6 the corrugations 6 lying at rightangles to the corrugations 5 so that if the hair in the region of theapplication of the hair pin is either run horizontally or verticallythey will be engaged by one set of corrugations which will prevent orreduce to a minimum the likelihood of the hair pin becoming accidentallydisenga ed from the hair.

f course I do not wish to be limited to the exact details ofconstruction as herein shown as these may be varied within the lim itsof the appended claim without departing from the spirit of my invention.

Having thus fully described my invention, what I claim as new and usefulis As an article of manufacture, a hair pin, comprising a single pieceof material bent upon itself to form spaced parallel central tangs andhaving their ends bent outward upon themselves, to form outer tangsspaced from the central tangs, said outer tangs being approximatelyparallel with the central tangs, said central tangs having corrugationslying in one direction and said outer tangs having corrugations lying atright angles to the first mentioned corrugations.

In testimony whereof I have hereunto affixed my signature.

FRED WALKER.
